Your symptom sounds like a damaged convergence IC.

There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

If your colors do not line up at all on the screen this is most likely the problem, and it can be repaired by replacing the convergence IC’s. This can be done but it is not the easiest repair to tackle, as there is associated resistors and coils that can open when the IC’s fail.

I usually recommend that both, or all three be replaced (depending on your set) because if one is bad the others are most likely close to going out too.

You may want to consult a Television Repair Technician, or repair this yourself. If you want to tackle this yourself, let me know, I can give you some direction for the repair.

I have done this repair for around $300.00, but you can get the parts for around $120.00. I recommend the OEM parts, as you can find very cheap IC’s that look just like the originals, but they will not last long.

I hope this information allows you to resolve this issue.

Mitsubishi VS-50609 - Red convergence is way off, suddenly


You have a bad ground on a convergence IC. You will have to carefully pull this board out and resolder the pins. If this does not solve the problem you will have to replace the ICs. I have saved a few of these TVs with just a resolder job. Thanks for asking!

Boe in blue dynamic convergence curcuitry. Swapped deflection yoke on two tubes but problem still remains. Unplugged convergence plug on yoke and bow disappeared but unable to adjust dynamic convergence....


what's the number of the board where you unplugged the conv yoke, should start with 930_ that is the board you need. Try the partstore.com with the part number or type in the brand and model when you have the number on the board, and they display price and availability.

My Mitsubishi vs-5061 isn't working properly. The red crosshair wont line up with the white ones going horizontally. The red is bowing. Causing most writting to have a double vision look. HELP!


Hi, this will occur when the convergence unit has failed . you will need to replace the convergence board in this unit in order to restore proper convergence functions. This is just below the optical assembly in the PCB main area next to the signal board and terminal block.
